CARRIAGE-KNOB.

Specification forming part of Letters Patent No. 48,373. datcd J une 27, 1865.

To all whom it may concern:

Be it known. thabI, R. I. COWLES, of New Haven, in the county of New Haven and State of Connecticut,;have invented a new and useful Improvement in the Manufacture of Carriage-Kndbs; and I d'0 hereby declare the following to be a full, clear, and exact descriptien of the same, when taken in connection with the accompanying drawings and the letters of reference marked thereon, and which said drawings constitute part of ths specification, and represent, in V Figure 1, a side view; Fig. 2, a central section, and in Figs. 3*and 4 the two parts detached. Heretofore carriage-knobs have been made by casting a met-al head onto a piece of pointed wire. Preparing the wire, molding and casting suchextremely light pieces, together with the fact that no inconsiderable amount cf labor was required to finish the casting, have rendered them comparatively an expensive a1- ticle.

T0 produce a more perfect article, andat much less cxpense, is the object of my inventian, which consists in the empoyment of a carriagetack as the head of the knob, passed through rose or bushing struck up from thn metal. 4

T0 enable others skilled in the art; [0 produce my improved carriagcknobs, I will propierced in the n'eck, aSseen in Fig. 2, pressing il; down nntil the head of the tack rests upon the neck and my knob is compiete, as seen in Fig. 1.

I prefer and usnally do cover the head of the tack with thin mctal. The metal covering cf the head, also the neck, may be formed from plated met-t1, cr left; plain, or jappaned, as desired, and of any size requred. Thus I have produced a mach more perfect knob t-i1an heretofore produced and at a comparativey trifling cost.

Having fully descriied my invention, what I claim as new and usefu], and desire to secnrc by Letters Patent, is-

The herein-described kn0b, as a new article 0f manufacture.
